But, this is the product I want, because I sell high end used luxury watches, and chargebacks are the biggest PITA and one of the hindrances to profitable growth in that sector.

Losing out on a large chunk of a $15k transaction because the buyer thinks the condition of the watch is "not as described" (where in reality, they know this is an easy way to scrape a huge discount on their purchase because the criteria is so subjective and petty) makes life very difficult. Sure, 95% of my customers are great, but that 5% really deals material damage when you are talking about high cost physical goods.

This product offering is interesting, and is worth investigating and weighing its cost against my average annual losses from chargebacks. In your case, you are offering SaaS so your marginal cost must be negligible. Different strokes for different folks I guess.
